This invention relates to a vacuum cleaner with the lowest power input. The fan 13 operated in Aconjunction with an automobile is formed from a central hexagonal hub 19 for the purpose ofproviding an easily availthrough which the shaft 15 passes, and the able means for cleaning the automobile, parblades or vanes of the fan, hei'e shown as six ticularly the interior upholstery and lining. in number are formed in three pairs With a The vacuum producing mechanism is short tie-piece 20 integrally interconnecting mounted in a convenient location in the aiithe inner ends of the blades in each pair. tomobile and is so constructed that it may The ties 20 are secured to every other iiat not be set in operation unless there is the surface of the hub by means of the screws 21.

The end of the hose 22 is fitted Fig. 1, is a side elevation of an automobile with an external ferrule 24 having an annuwith a fragment of its side removed; lar groove 25 therearound. 65

At all times other than in actually :leaning the automobile, the hose 22 is al- Ways disconnected and kept out of sight.

The invention can of course assume several forms, as for one example, the nipple 16 5 may be kept back of the face of the panel 1Q and the switch 26 incorporated Within the panel or behind it to -be concealed from sight.

TWe Claim: A y

l. In a, vacuum cleaner operated by an electric motor and having an intake fitting, :t hose adapted to slide over said iitting, a switch controlling said motor, and a plunger operating said switch normally projecting toward seid fitting, a ferrule on the end of the hose having an annular depression therezuouml, whereby the sliding of said hose over said fitting Causes said hose to press said plunger away from said fitting and close seid switch and to have the end of said plunger resting in said depression to yieldingly retain the hose on said fitting.

2. ln u niotor (lriven vue-umn cleaner, :In intake nozzle, :L hose adapted to slide over the nozzle, nn eleetrie switch normally open, n switch iwtuut'iner plunger adapted to travel nornnill)v of said nozzle, said plunger being yielllinely preseefl back away from said nozzle to (tiene Suid switch upon positioning' Suid hose on the nozzle und ineens by which the plunger retains the hose 0n the. nozzle.

3. `ln :t motor driven Yncuuni cleaner, :1n intake nozzle, e hose adapted to slide over the nozzle. :in electric Switch normally open,
